This is just a regular QObject-based class. All private slots are test cases (like in QTestLib). The only special thing is the "TESTSUITE" annotation just before the class name. That's it. (You only need to link against CuteTest and QtCore for this to run. See the examples provided by the project.)

Additionally to the test API CuteTest provides you with a console and a GUI frontend (that are built on CuteTest's API). Especially the GUI frontend make viewing test results much easier than with QTestLib's console output.
